Centos-ds directory console problem
by guy＠desgames.com 28 Sep '10

28 Sep '10

I installed centos-ds on a 5.5 installation, following the instructions to a tee, however now when I log onto the Directory Console I only get the Servers and Applications and Users and Groups tabs - no Configuration or Tasks tabs. Initially I was using the wrong password for the Directory Manager user, but when I put in the correct password it just sat there saying "Authenticating Directory Manager..." (something like that). So I followed the instructions to change the password, but now it just does the same thing as before - lets me in, but with no Configuration or Tasks tabs. Obviously I'm being logged in as just an admin user as I can add users, groups and ou's to the tree. Any help on this would be most appreciated. Thanks, Guy

ethtool
by m.roth＠5-cent.us 28 Sep '10

28 Sep '10

We've just moved one a new server from our sever room, where I built it, to the datacenter. We want to force autoneg off, and tell it gigabit and full duplex. Using ethtool, I get no errors setting the speed or duplex. HOWEVER, autoneg on works... and autoneg off utterly refuses to work, and gives: ethtool -s eth0 autoneg off Cannot set new settings: Invalid argument not setting autoneg We're on the most current update of CentOS (ok, last kernel, that will come up on the reboot I'll do shortly), and it's a Broadcom Corporation NetXtreme II BCM5716 Gigabit Ethernet Anyone have an idea what's going on here? mark

So I'm in the process of building and testing a raid setup and it appeared to take along time to build I came across some settings for setting the min amount of time and that helped but it appears that one of the disks is struggling (100 utilization) vs the other one...I was wondering if anyone else has seen this and if so, is their a solution for it...my 2 disks are 1 Samsung F3 1tb /dev/sdb and 1 Seagate 7200.12 1Tb /dev/sdc...smartctl looks good on both.... sar -dbpqu -P ALL 60 1 Linux 2.6.18-194.11.4.el5 (dpcserver) 09/27/2010 10:09:41 AM CPU %user %nice %system %iowait %steal %idle 10:10:41 AM all 0.03 0.00 1.11 0.00 0.00 98.86 10:10:41 AM 0 0.00 0.00 0.00 0.00 0.00 100.00 10:10:41 AM 1 0.10 0.00 1.25 0.00 0.00 98.65 10:10:41 AM 2 0.00 0.00 3.18 0.02 0.00 96.80 10:10:41 AM 3 0.00 0.00 0.02 0.00 0.00 99.98 10:09:41 AM tps rtps wtps bread/s bwrtn/s 10:10:41 AM 838.27 836.41 1.87 107059.98 32.54 10:09:41 AM DEV tps rd_sec/s wr_sec/s avgrq-sz avgqu-sz await svctm %util 10:10:41 AM sda 0.93 0.00 16.27 17.43 0.00 2.12 0.29 0.03 10:10:41 AM sda1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 10:10:41 AM sda2 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 10:10:41 AM sda3 0.93 0.00 16.27 17.43 0.00 2.12 0.29 0.03 10:10:41 AM sdb 209.10 26764.99 0.00 128.00 30.90 148.02 4.78 100.02 10:10:41 AM sdb1 209.10 26764.99 0.00 128.00 30.90 148.02 4.78 100.02 10:10:41 AM sdc 209.10 26764.99 0.00 128.00 0.41 1.94 0.60 12.57 10:10:41 AM sdc1 209.10 26764.99 0.00 128.00 0.41 1.94 0.60 12.57 10:10:41 AM md0 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 10:09:41 AM runq-sz plist-sz ldavg-1 ldavg-5 ldavg-15 10:10:41 AM 0 167 1.02 1.03 1.00 Thanks in advance.....

how to get ASUS USB-N13 802.11n net adapter working on 5.5?
by Robert P. J. Day 28 Sep '10

28 Sep '10

first, the short form of the question -- has anyone got that wireless adapter working on centos 5.5 and associated with an access point that uses WPA/WPA2 security? and the details. in a classroom where there is *no* wired networking at all, all PCs have only that wireless net adapter, which works fine on windows but, after installing centos 5.5, unsurprisingly, we have no networking. there is no backup wired network, and no other adapters. there is a CD that came with the adapters, with a Linux directory, so it was easy enough to dump that onto my personal centos 5.5 box, and run "make" which generated the loadable "rt3070sta.ko" module. and, yes, that module loads. so far, so good. however, that still doesn't do it as based on what i've read online), because the access point here uses WPA/WPA2, i need to use wpa_supplicant to be able to configure the wireless interface for that. and that's about when i got kicked out of the classroom as they were closing for the evening. thoughts? any advice humongously appreciated. rday -- ======================================================================== Robert P.

Dell HSPA 5530 - Built-in 3G - Not detected
by Janne Nyman 28 Sep '10

28 Sep '10

Hi all, I have been trying to get CentOS 5.5 running on my Laptop for a while now. I am currently running Fedora 13 for the only reason that my Dell Wireless HSPA 5530 built-in 3G Mobile Device is working. I have tried loading the bcm43xx modules after reading several posts on Google but not able to get this working at all. I have run CentOS on my servers for a while now and love it. Just this last bit that holds me back from going fullt to CentOS. My laptop is a Dell E6400 and I have tried with both x86 and x86_64 without luck. Has anyone else got this working or have any clues to the steps I can take to get closer to a working solution? -- Rgds, Janne Nyman E: jnyman(a)jbtec.org

logwatch question
by lostson 28 Sep '10

28 Sep '10

Hello A few weeks ago I started having problems with my system email or specifically my logwatch reports showing up in my inbox. I got most of those issues figued out except one now when i get an email from my system it has a title of this Cron <root@localhost> run-parts /etc/cron.daily with this message /etc/cron.daily/0logwatch: Recipient names must be specified I have my aliases set right and have been googling for an answer and just cant seem to find anything pointing me in the right direction. But this has been going on for awhile now and i would like to get my normal reports back that i used to get. I have never had to do much else except set my aliases file up correctly and i just always got the daily reports. I am probably missing something amazingly simple but i just cant seem to find it any ideas, thanks. LostSon http://lostsonsvault.org

Question on installing .run file
by Jerry Geis 28 Sep '10

28 Sep '10

I am trying to automate the install of the ati driver package. Basically all I do is hit return about 6 times and take all the defaults. I tried to do this in a file that I then made executable with 744: sh ati-driver-installer-10-8-x86.x86_64.run << EOF EOF but then it starts like its doing something but never does anything. How might I automate such an install script. Again all I do is hit return 6 times and accept all the defaults. Thanks, Jerry

(In)(x)sane privilege/access issue
by Mark 27 Sep '10

27 Sep '10

I just picked up a new HP OfficeJet J3680 all-in-one (because, as previously posted, my 4315 broke), and I was able to install the printer using the latest hplip's hp-setup command, BUT: My sane: libsane-hpaio.x86_64 1.6.7-4.1.el5.4 installed sane-backends.x86_64 1.0.18-5.el5 installed sane-backends-devel.i386 1.0.18-5.el5 installed sane-backends-devel.x86_64 1.0.18-5.el5 installed sane-backends-libs.i386 1.0.18-5.el5 installed sane-backends-libs.x86_64 1.0.18-5.el5 installed sane-frontends.x86_64 1.0.14-1.2.2 installed xsane.x86_64 0.991-5.el5 installed xsane-gimp.x86_64 0.991-5.el5 installed doesn't recognize that there is a scanner out there and only loads the interface for my old ScanJet 3300C: [mar@marichter ~]$ lsusb Bus 001 Device 001: ID 0000:0000 Bus 002 Device 012: ID 03f0:0205 Hewlett-Packard ScanJet 3300c Bus 002 Device 006: ID 04f9:0033 Brother Industries, Ltd Bus 002 Device 001: ID 0000:0000 In fact, the new scanner doesn't even show up unless: [mar@marichter ~]$ sudo lsusb [sudo] password for mar: Bus 001 Device 001: ID 0000:0000 Bus 002 Device 015: ID 03f0:3112 Hewlett-Packard Bus 002 Device 012: ID 03f0:0205 Hewlett-Packard ScanJet 3300c Bus 002 Device 006: ID 04f9:0033 Brother Industries, Ltd Bus 002 Device 001: ID 0000:0000 If I run xsane from the command line as root (i.e., with sudo), then it works, but then I also get that WARNING DANGER WILL ROBINSON message, which is both annoying and probably likely to cause problems with file permissions on my scans. So, how do I (a non-root user) get x/sane to see the new USB device when it only appears to visible to the root user? What am I missing? Thanks. Mark

Bugzilla 3.6.2 + sendmail + SELinux
by Mathieu Baudier 27 Sep '10

27 Sep '10

Hello, I have deployed Bugzilla 3.6.2 on CentOS 5 (with rpmforge perl-* packages) and I have a problem with SELinux preventing mail being sent via sendmail. (see SELinux reports below, especially the second one) When SELinux is in permissive mode, mail sending from Bugzilla is working properly. Has anybody got recent Bugzilla to work with SELinux on CentOS? Thanks in advance! Mathieu -------------------------------------------------------------------------------- Summary: SELinux is preventing the sendmail from using potentially mislabeled files ./spool (var_spool_t). Detailed Description: SELinux has denied the sendmail access to potentially mislabeled files ./spool. This means that SELinux will not allow httpd to use these files. Many third party apps install html files in directories that SELinux policy cannot predict. These directories have to be labeled with a file context which httpd can access. Allowing Access: If you want to change the file context of ./spool so that the httpd daemon can access it, you need to execute it using chcon -t httpd_sys_content_t './spool'. You can look at the httpd_selinux man page for additional information. Additional Information: Source Context system_u:system_r:httpd_bugzilla_script_t Target Context system_u:object_r:var_spool_t Target Objects ./spool [ dir ] Source sendmail Source Path /usr/sbin/sendmail.sendmail Port <Unknown> Host <Unknown> Source RPM Packages sendmail-8.13.8-8.el5 Target RPM Packages Policy RPM selinux-policy-2.4.6-279.el5_5.1 Selinux Enabled True Policy Type targeted MLS Enabled True Enforcing Mode Enforcing Plugin Name httpd_bad_labels Host Name www Platform Linux www 2.6.18-194.11.4.el5 #1 SMP Tue Sep 21 05:04:09 EDT 2010 x86_64 x86_64 Alert Count 1 First Seen Mon Sep 27 02:07:43 2010 Last Seen Mon Sep 27 02:07:43 2010 Local ID 24372577-2d4c-4bbe-be6b-ea9100b7c3ed Line Numbers 11701, 11702 Raw Audit Messages type=AVC msg=audit(1285546063.60:15): avc: denied { search } for pid=3420 comm="sendmail" name="spool" dev=dm-2 ino=158722 scontext=system_u:system_r:httpd_bugzilla_script_t:s0 tcontext=system_u:object_r:var_spool_t:s0 tclass=dir type=SYSCALL msg=audit(1285546063.60:15): arch=c000003e syscall=80 success=no exit=-13 a0=7fffeddf6060 a1=17 a2=fff a3=0 items=0 ppid=3418 pid=3420 auid=4294967295 uid=48 gid=48 euid=48 suid=48 fsuid=48 egid=51 sgid=51 fsgid=51 tty=(none) ses=4294967295 comm="sendmail" exe="/usr/sbin/sendmail.sendmail" subj=system_u:system_r:httpd_bugzilla_script_t:s0 key=(null) -------------------------------------------------------------------------------- Summary: SELinux is preventing sendmail (httpd_bugzilla_script_t) "create" to <Unknown> (httpd_bugzilla_script_t). Detailed Description: SELinux denied access requested by sendmail. It is not expected that this access is required by sendmail and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. Allowing Access: You can generate a local policy module to allow this access - see FAQ (http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable SELinux protection altogether. Disabling SELinux protection is not recommended. Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.

couple questions about initrd.img
by Robert P. J. Day 27 Sep '10

27 Sep '10

here's hoping this is on topic. as part of the extra goodies i'm going to give my RHEL/centos basic admin class this week, i'm going to get them to open up the standard initrd.img file and see what's inside. i just did that myself and have a couple simple questions. first, while the cpio archive physically contains a number of basic /dev special files, the top-level "init" script runs "mknod" to create them all, anyway. not a big deal, but is it fair to say that populating the initrd.img with those initial /dev files is redundant since init creates them all, anyway? also, i note that that "init" script appears to call a couple scripts/commands that don't exist in the initrd, such as hotplug and mkblkdevs. again, not a big deal but if i show the students what's in that initrd, chances are someone's going to notice the above and ask about it, so i might as well have an answer. thanks. rday -- ======================================================================== Robert P.

Configuring BIND to answer to two domain names (four IP addresses)
by Dotan Cohen 26 Sep '10

26 Sep '10

On a CentOS 5 server, I am having a hard time configuring BIND to answer to 4 IP addresses for 2 domain names. Currently, I have four IP addresses, for sake of discussion they are: 1.1.1.1 1.1.1.2 1.1.1.3 1.1.1.4 Additionally, I have two domain names. For sake of discussion: exampleA.com exampleB.com My goal is to have 1.1.1.1 & 1.1.1.2 as the nameservers for exampleA.com, and 1.1.1.3 & 1.1.1.4 as the nameservers for exampleB.com. Apache is running on this machine, and should of course serve pages for the sites. I think that I've got the apache configuration down, but the BIND configuration is eluding me. I've read the following fine manual, but I am still stuck: http://www.centos.org/docs/5/html/Deployment_Guide-en-US/ch-bind.html Additionally, I have googled for "how to configure bind for multiple domain names" and the like, but I see no mention of the IP addresses configuration. Can I simply configure any IP address that the server answers to as the nameservers? What am I missing? Thank you in advance! -- Dotan Cohen http://gibberish.co.il http://what-is-what.com

does having a centos wiki acct grant edit access?
by Robert P. J. Day 25 Sep '10

25 Sep '10

i just registered for a centos wiki account, and was wondering if this gives me edit capability. i'm prepping for the first of a number of RHEL/centos basic admin courses and currently working my way thru the wiki, collecting neat tricks and ideas and, occasionally, i'll stumble over typoes -- some minor, some not so much. for instance, here: http://wiki.centos.org/TipsAndTricks/YumAndRPM#head-61731905d2e34ac343baeef… the command is listed as: yum --disable "*" --enable "rpmforge" list available i'm guessing that should actually be: yum --disablerepo "*" --enablerepo "rpmforge" list available no? but even if i got edit access, i'd still be happier if someone eventually checked out any changes i made to validate them. whatever works best. rday -- ======================================================================== Robert P.

I am able to cat it: [code] [bluethundr@LBSD2:~]$:ssh root@sum1 cat /root/id_rsa.pub root(a)lcent01.summitnjhome.com's password: ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEApnUSYyrM96qIBZKjwSNYycgeSv/FAKE-KEY-DATA--KEY-DATA-PWReyVuOn9Fb/uH/FAKE-KEY-DATA-+ttLzUELGrfn/n+FAKE-KEY-DATA-/FAKE-KEY-DATA-/FAKE-KEY-DATA-/FAKE-KEY-DATA-== bluethundr(a)lbsd8-2.summitnjhome.com [/code] But I cannot cat / grep it in order to determine if this key is already in the authorized_hosts file of the remote host. [code] [bluethundr@LBSD2:~]$:ssh root@sum1 grep `cat /root/id_rsa.pub` /root/.ssh/id_rsa.pub root(a)lcent01.summitnjhome.com's password: /root/.ssh/id_rsa.pub:ssh-rsa ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEApnUSYyrM96qIBZKjwSNYycgeSv/FAKE-KEY-DATA--KEY-DATA-PWReyVuOn9Fb/uH/FAKE-KEY-DATA-+ttLzUELGrfn/n+FAKE-KEY-DATA-/FAKE-KEY-DATA-/FAKE-KEY-DATA-/FAKE-KEY-DATA-== bluethundr(a)lbsd8-2.summitnjhome.com==: No such file or directory grep: root@bt-laptop: No such file or directory [/code] Ultimately, what I would like to do is script this in order to automate this process: [code] #!/bin/sh HOSTS="sum1 sum2 virt1 virt2 virt3 virt4 virt5 virt6 virt7" SSHDIR=~/.ssh RSYNC=/usr/local/bin/rsync KEYFILE=/home/bluethundr/.ssh/id_rsa.pub CAT='/bin/cat' GREP='/bin/grep' for h in $HOSTS ; do scp $KEYFILE root@$h:~/ if [ $? = 0 ]; then echo ; echo ; echo echo "KEY TRANSFERRED TO $h" else echo "KEY Transfer To $h has FAILED" exit 1 fi ssh root@$h $CAT /root/id_rsa.pub | $GREP -i /root/.ssh/authorized_keys if [ $? = 1 ]; then ssh root@$h $CAT /root/id_rsa.pub >> /root/.ssh/authorized_keys if [ $? = 0 ]; then echo ; echo ; echo echo "KEY APPENDED TO $h Authorized Hosts" else echo "KEY APPEND FAILED" fi exit 1 fi done [/code] This is what results from the above script: [code] [bluethundr@LBSD2:~/bin]$:./key-export.sh root(a)lcent01.summitnjhome.com's password: id_rsa.pub 100% 417 0.4KB/s 00:00 KEY TRANSFERRED TO sum1 ./key-export.sh: /bin/grep: not found root(a)lcent01.summitnjhome.com's password: [/code] And I'm pretty sure I have those variables set correctly in order to execute those commands: [code] [bluethundr@LBSD2:~/bin]$:ssh root@sum1 root(a)lcent01.summitnjhome.com's password: Last login: Fri Sep 24 07:34:02 2010 from 192.168.1.44 ######################################################### # SUMMITNJHOME.COM # # TITLE: LCENT01 BOX # # LOCATION: SUMMIT BASEMENT # # # ######################################################### [root@LCENT01:~]#which grep /bin/grep [root@LCENT01:~]#which cat /bin/cat [/code]

mcelog
by m.roth＠5-cent.us 24 Sep '10

24 Sep '10

Ok, we've got a new machine that's throwing ECC errors. I've gotten new memory overnighted to me from the manufacturer, and replaced it, oops, not that end of the bank, as their support told me, this end of the bank, as the mobo manual I found online shows (Supermicro). Still throwing errors. Ok, try to get more info.... Last week, I moved /var/log/mcelog to /var/log/mcelog.1, and touched /var/log/mcelog. This week, I tried running mcelog manually, and via /etc/cron.hourly/mcelog, and get *nothing* at all. /var/log/message only screams that there are ECC errors, so I need more data. I've even tried reinstalling mcelog, but no joy. Anyone got any ideas here, how to get it to say something? mark

performance and interrupts
by Mag Gam 24 Sep '10

24 Sep '10

I am playing around with irqbalance to tune my 8 core system so I came across this page, http://kb.fusionio.com/KB/a65/irqbalance-avoid-overloading-cpu-0-with-inter… Now, lets say I disable irqbalance which will stop my autobalance and I pin all of my interrupts to core 0 and pin eth0 and eth1 to core 1. My application is network and CPU hungry. I am planning to dedicate cpu 3 to 8 for the application using taskset. Is there any draw back to this?

Thank you *SO* much! I needed some real world evidence to prove that syncing large amounts of data across windows is a PITA! I'm currently doing something so similar!

Disabling IPv6 Auto Configuration
by Ryan Wagoner 24 Sep '10

24 Sep '10

I am using stateless auto configuration for most of my clients. For the servers I prefer to manually assign the address. I have defined the IPv6 address in the ifcfg-eth0 file and set IPV6_AUTOCONF=no. However ifconfig shows both the auto configured and manually assigned address. Looking around I found that net.ipv6.conf.default.accept_ra is set to 1 by default. The ifup-ipv6 is setting net.ipv6.conf.eth0.accept_ra to 0 like it should. From what I can tell the auto configuration is happening right before net.ipv6.conf.eth0.accept_ra is set to 0. If I define net.ipv6.conf.default.accept_ra = 0 in sysctl.conf IPV6_AUTOCONF works as expected for both yes and no settings. Has anybody else noticed this behavior? Ryan

CentOS, Firefox, and Java Plugin
by Glenn Eychaner 23 Sep '10

23 Sep '10

The latest updates to CentOS 5.5 seem to have broken the Java plugin, and have defeated any and all attempts to get it working again. I'm running CentOS 5.5 (32-bit) and Firefox 3.6.9 (installed from the CentOS repository); I've tried BOTH the openJDK plugin available through the Argeo repositories, and installing Java 1.6.0 directly from Sun/Oracle and creating the plugin soft link in /usr/lib/mozilla/plugins. Neither works at all. This was working a while ago, but it broke and I didn't notice. Thanks for any help you can provide, -G. -- Glenn Eychaner (geychaner(a)lco.cl) Telescope Systems Programmer, Las Campanas Observatory

Logwatch verbosity

I'm getting literally hundreds of lines in my daily logwatch (under Centos-5.5), reading --------------------------------------- NULL security context for user, but SELinux in permissive mode, continuing () --------------------------------------- These began when I started running fail2ban (with shorewall), though that is probably a coincidence. In any case, what does this line mean, and is there any way of stopping it (short of stopping selinux)? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity ollege, Dublin 2, Ireland

using NUT on centos 5
by fred smith 21 Sep '10

21 Sep '10

Hi! Trying to set up NUT on Centos 5 to monitor a CyberPower 1500AVR UPS. There seem to be many documents, all of which seem to be not fully consistent with each other, and most of them aren't up to date. I'm guessing I should be using udev rather than hal, but I'm somewhat stumped on how to figure out what device it should be monitoring. there are a bunch of udev rules installed (in /lib/udev/rules.d/52-nut-usbups.rules) but it's not at all clear to me what, if anything, I'm supposed to do with them, or how I cause udev to see them there and do its thing. there's a document at http://fedoranews.org/contributors/kazutoshi_morioka/nut/ but it doesn't show how to do it with a USB device, only serial. so I decided to move on and see if it could be made to work without that understanding, using whatever I could figure out using the INSTALL file that comes with NUT. And that isn't geting me anywhere, so far. If anyone out there has had success at setting up NUT on Centos 5 (or RHEL) and can offer any advice, I'd appreciate hearing from you. Thanks in advance! -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ----------------------------- "For him who is able to keep you from falling and to present you before his glorious presence without fault and with great joy-- to the only God our Savior be glory, majesty, power and authority, through Jesus Christ our Lord, before all ages, now and forevermore!

Sendmail TLS verify=fail
by Morten P.D. Stevens 21 Sep '10

Hi, I have a small question with sendmail and tls verification. The tls verify fails on our internal/external sendmail servers. For example: STARTTLS=server, relay=mx1.imt-systems.com [89.146.219.60], version=TLSv1/SSLv3, verify=FAIL, cipher=DHE-RSA-AES256-SHA, bits=256/256 STARTTLS=server, relay=acsinet12.imt-systems.com [89.146.219.42], version=TLSv1/SSLv3, verify=FAIL, cipher=DHE-RSA-AES256-SHA, bits=256/256 What's the problem? The sendmail tls certificate should be okay on both servers.

Software RAID + LVM + Grub
by Matthew Topper 21 Sep '10

21 Sep '10

I'm playing with software RAID and LVM in some virtual machines and I've run into an issue that I can't find a good answer to in the docs. I have the following RAID setup: md0: sda1 and sdb1, RAID 1. This is /boot md1: sda2 and sdb2, RAID 1. This is a PV for LVM. VolGroup00, this is the volume group and md1 is the only PV in it. LogVol00 is swap LogVol01 is / LogVol02 is /home So, I tested to see what happens if I disable sdb in virtualbox. Machine booted find and I was able to see that part of the raid array was gone. I reattached the disk and rebuilt the array mdam --add /dev/md0 /dev/sdb1 mdam --add /dev/md1 /dev/sdb2 The array rebuilt without issue. But now, if I remove sda, the machine doesn't boot and grub complains. The question I have is how does one reinstall the boot sector at this point? I'm a little confused as far as to what device to install it on and what to specify as the root. This is grub.conf if it helps: default=0 timeout=5 splashimage=(hd0,0)/grub/splash.xpm.gz title CentOS (2.6.18-194.e15) root (hd0,0) kernel /vmlinuz-2.6.18-194.e15 ro root=/dev/VolGroup00/LogVol01 initrd /initrd-2.6.18-194.e15.img Grub has always been a little confusing for me, so I guess I don't understand. What do the two root entries specify? And again, my main question is how do I reinstall grub to the repaired disk? Sorry for the lengthy post, I'm trying to provide as much information as possible.

Gnome mouse configuration.
by James B. Byrne 20 Sep '10

20 Sep '10

On my Centos-5.5 (x64) based desktop the optical mouse I originally configured during the system install has died. In /etc/sysconfig/hwconf this is configured as: class: MOUSE bus: USB detached: 0 device: input/mice driver: genericwheelusb desc: "Microsoft Microsoft 3-Button Mouse with IntelliEye(TM)" usbclass: 3 usbsubclass: 1 usbprotocol: 2 usbbus: 4 usblevel: 1 usbport: 0 usbdev: 4 vendorId: 045e deviceId: 0053 usbmfr: Microsoft usbprod: Microsoft 3-Button Mouse with IntelliEye(TM) I have replaced the failed mouse with a spare from our surplus parts cabinet and now the centre wheel/button click no longer inserts selected text at the current cursor position. I would like to obtain this feature with the replacement mouse, which is described on the bottom as a MicroSoft Optical Mouse Blue USB and PS/2 compatible. It has a usb connector which is plugged directly into the chassis usb port. All the other features of the mouse seem to work just fine. I simply cannot obtain the centre button click insert capability. Is there no way to simply force CentOS-5 to re-detect the attached mouse? It must have done something akin to this during the initial install. I tried running kudzu as root from a gnome terminal session but that had no effect that I can detect. -- *** E-Mail is NOT a SECURE channel *** James B.

How to simulate minimal ISO install using stage2 image file?
by Chad Woolley 20 Sep '10

20 Sep '10

Hello, I'm working on a project which automates creation of EC2 AMI images. To do this, you must use a running EC2 instance to mount an image file in a chroot jail. My problem is that I want to create an AMI that looks exactly like a minimal (nothing selected) install from the CentOS ISO image, but the "stage2" image [1] file is much more "minimal" than that. e.g., it doesn't have yum, groups, devices, networking, etc set up as you would if you had run the ISO minimal install on a real or virtual box. I can't mount the ISO directly in the chroot (as far as I know, but I could be wrong). My question is, how can I make the mounted stage2.img chroot jail look just like a minimal ISO install? I could manually create everything (which I have started), but this is a lot of work, and I'm likely to miss something that an ISO build would have (e.g. some group). Is there some other standard CentOS script I can run after mounting the stage2.img which will do everything the installer does? Can I run the installer manually with some kickstart script? Pointers to references and documentation are welcome... Thanks, -- Chad [1] http://mirrors.usc.edu/pub/linux/distributions/centos/5.5/os/x86_64/images/

Using Make in frequent cron job
by Kenneth Porter 20 Sep '10

20 Sep '10

Is there a way to get Make to be silent when it does nothing, but have its normal verbosity when something is made? I want to use Make in a frequent cron job (every 1/2 hour, perhaps 10 minutes) but I don't want to get a bunch of emails telling me nothing was done (which will be most of the time). I just want to know when it found something to do.

You can write a wrapper script and run it in a subshell to capture the output.
